As the nationwide discourse on medical marijuana evolves, with 28 out of 50 states approving its use, University of Massachusetts Medical School graduates will need to be prepared to discuss medical marijuana (MMJ) with their patients. There is currently no formal medical school education on MMJ. This project set out to understand the curriculum gap and provide a learning session to interested students. The presentation was created using research done by the author during the first three years of medical school, including visits to private MMJ clinics. Utilizing a pre/post-session online assessment of a group of twenty-six students, we found that student knowledge about Massachusetts’ MMJ law improved by 29%, following a ninety-minute session. In addition, self-assessed confidence in negotiating clinical scenarios involving marijuana improved by 34%. These improvements were statistically significant, with p-values of 0.0033 and 9.5x10^-16 respectively. These findings support the formal addition of a sixty- to ninety-minute session focusing on MMJ to the UMMS curriculum.
